F41Generator Port Overload

Name in the manufacturer's documentation (user manual): Generator Port Overload[1]

In plain words (editorial)

The generator port is overloaded – the off-grid output exceeds the datasheet limits, there is a short circuit on the off-grid side, or the off-grid terminal voltage is too low.

When to call a service technician: Reduce the connected load; if it persists, contact your installer.
